Libxdp function xdp_program__find_file

Definition

Return the xdp_program associated to a filename and section names. The filename is without the PATH, it will automaticcaly look at LIBXDP_OBJECT_PATH.

Note

By default, LIBXDP_OBJECT_PATH is set to /usr/lib/bpf (alternatively /usr/lib64/bpf or /usr/local/lib/bpf, depending on the PREFIX libxdp was compiled with)

Note

When libxdp is compiled with the DEBUG flag, it will additionally look for BPF object files in the current directory, before checking the system-wide directory. This should not be used in production, as shadowing of system BPF programs can be a security issue.

Note

If you want to use a specific path, you can use xdp_program__open_file

Returns

struct xdp_program on success, or a negative error in case of failure

Usage

struct xdp_program *xdp_program__find_file(const char *filename, const char *section_name, struct bpf_object_open_opts *opts);
